"Yes, it's a very vague notion . . . but, all the same . . . Look here, there's one thing I forgot to tell you. Do you know why I joined the hospital in the Champs-Élysées, the hospital where you were lying wounded and ill? It was because Siméon took me there. He knew that I wanted to become a nurse and he suggested this hospital. . . . And then, if you think, later on, the photograph in the pendant, the one showing you in uniform and me as a nurse, can only have been taken at the hospital. Well, of the people here, in this house, no one except Siméon ever went there. . . . You will also remember that he used to come to Salonica, where he saw me as a child and afterwards as a girl, and that there also he may have taken the snapshots in the album. So that, if we allow that he had some correspondent who on his side followed your footsteps in life, it would not be impossible to believe that the unknown friend whom you assume to have intervened between us, the one who sent you the key of the garden . . ." "Was old Siméon?" Patrice interrupted. "The theory won't hold water." "Why not?" "Because this friend is dead. The man who, as you say, sought to intervene between us, who sent me the key of the garden, who called me to the telephone to tell me the truth, that man was murdered. There is not the least doubt about it. I heard the cries of a man who is being killed, dying cries, the cries which a man utters when at the moment of death." "You can never be sure." "I am, absolutely. There is no shadow of doubt in my mind. The man whom I call our unknown friend died before finishing his work; he died murdered, whereas Siméon is alive. Besides," continued Patrice, "this man had a different voice from Siméon, a voice which I had never heard before and which I shall never hear again." Coralie was convinced and did not insist. They were seated on one of the benches in the garden, enjoying the bright April sunshine. The buds of the chestnut-trees shone at the tips of the branches. The heavy scent of the wall-flowers rose from the borders; and their brown and yellow blossoms, like a cluster of bees and wasps pressed close together, swayed to the light breeze. Suddenly Patrice felt a thrill. Coralie had placed her hand on his, with engaging friendliness; and, when he turned to look at her, he saw that she was in tears. "What's the matter, Little Mother Coralie?" Coralie's head bent down and her cheek touched the officer's shoulder. He dared not move. She was treating him as a protecting elder brother; and he shrank from showing any warmth of affection that might annoy her. "What is it, dear?" he repeated. "What's the matter?" "Oh, it is so strange!" she murmured. "Look, Patrice, look at those flowers."
